A two-alternative forced-choice task, where subjects choose between gambles to accumulate secondary rewards (tokens). Subjects see two, asynchronously presented gambles, each characterized by two possible outcomes and one probability. Gambles yield a gain or loss of tokens, which accumulate across trials. Collection of six tokens leads to the receipt of a large primary reward (water).
